BACKGROUND OF INVENTION

Accurate diagnosis of a personal level of overload activity is required besides obvious sports and medical applications in stressful situations in order to prevent them. Activity estimation is based on the heart rate and there are two major currently existing heart rate monitors HRM: wrist-based and chest-strap. The very earliest technical solutions for placed over the carpal tunnel wrist pulse monitor with infra-red sensor to pick up the flow of blood therein and radio frequency transmitter to transfer data to a display unit which processes it and displays pulse is cited in U.S. Pat. No. 5,810,736 B1. Quite elegant assembly of wrist pulse monitor with additional piezoelectric sensing elements to eliminate power drain from light emitting diode (LED) and thus more complete noise reduction resulting in reading accuracy is proposed in U.S. Pat. No. 5,807,267 B1.

More sophisticated digital apparatus for detecting arrhythmia by analyzing the continuity of change in pulse waveform is suggested in U.S. Pat. No. 6,095,984 B1. Incorporated into device body motion detection means allow accurate arrhythmia monitoring. This device is developed to a higher degree in U.S. Pat. No. 9,597,004 B2 where advanced technological solution allows two-way communication with a server configured and monitored by a cardiologist in case the user initiated the trigger. Device configuration aims constant heart rate and EKG data collection mostly for diagnostic or intense care purposes. Change of patient condition due to aging or new medication prescription requires new appointments and server update. Moreover, amount of volunteers wishing to be monitored by same cardiologist is limited, while provided service could be expensive.

In U.S. Pat. No. 6,580,942 B1 a chest apparatus for detecting an activity of a human heart operates on proposed circuit which analyzes signals received from the sensors and upon determination that such signals are of electrographic nature, i.e. derived from heart beats, generates an alert. This invention is fitting best patient monitoring before during and after surgical or medical treatment at the hospital. Such approach is further advanced in U.S. Pat. No. 9,566,007 B2 proposing a method and based on it a wearable device for continuously and accurately monitoring ECG and photo-plethysmograph waveform to determine a patient's vital signs. Wrist and chest detectors comprised with an analyzer module and blood pressure measuring by pulse transmit time technique require multiple electrodes attached to the patient's chest. This ultimately restricts the movement capability of the user but makes the device a valuable addition to an operation room.

U.S. Pat. No. 6,042,549 B1 is disclosing a personal device for measuring exercise intensity and quantity based on the user pulse which limits are computed and set up from preliminary test of maximum oxygen consumption rate. This method and device is rather for professional athletes undergoing intense training and being observed by qualified medical personnel. A method for monitoring a cardiac status during intense exercise is suggested in U.S. Pat. No. 9,566,010 B2 where proposed algorithm is based on related to cardiac output cardio force index normalized to cardiac force index at walking. Such training (or self-training) apparatus functionality fully depends on measured acceleration during walking, input weight of the user, and preset maximum activity level. Unfortunately, definitions of neither acceleration during walking with constant speed, nor individual maximum activity level are specified.

U.S. Pat. No. 9,430,615 B2 depicts a device that goes beyond the scope of a wearable monitor. It is a personal phone, playing music, or watching videos device configured to utilize measured by two electrodes EKG signals and monitoring method for detecting heart rate anomalies in the background during use and alerting proper authorities in case irregularity occurs. The shortcoming of the device is that it does not take into account the distinctiveness of each user heart rate based on upon their medical history. Therefore, the definition of “anomaly” is not personal and could result in many false positives.

In general, none of the existing heart rate monitoring devices is capable of predicting personal level of dangerous activity and alarm the user of its approach. Moreover, closely related to pulse issues such as continuous blood pressure and metabolic rate estimations have never been a features of any heart rate monitoring device.

SUMMARY OF INVENTION

Proposed new personal device allowing continuous monitoring and diagnosing user activity accompanied by estimation of blood pressure and metabolism.

The working principle of this device is based on developed unique and efficient method to accurately evaluate personal heart rate and blood pressure at over stressed, or maximum allowed physical or mental activity for an individual of a given build, fit, age, and gender with certain health conditions and heart rate at rest.

Based on personal input (automatically updated or manually reset) and instantaneous heart rate device is constantly

-   -   compares it with the individual heart rate at maximum activity         (over stressed zone) and issues warnings in order to avoid         dangerous unhealthy situation;     -   estimates and saves blood pressure data with the option of         transferring it to an authorized party;     -   computes user energy consumption and estimates amount of daily         weight loss or gain;         thus, monitoring three the most crucial health issues—individual         activity, medical conditions, and dieting never been presented         together in one device suitable for any adult and surely helpful         for any physician.

B: Development of Relevant Solutions

In order to function body needs energy which is coming from oxygen delivered by blood flow called cardiac output CO. Hence, energy consumption has to be proportional to cardiac output. There are two basic equations involving CO:

and

$\begin{matrix} {{CO} = {{SV}*{HR}}} & \left( {{Eq}.\mspace{14mu} 1} \right) \\ {{CO} = \frac{MAP}{R}} & \left( {{Eq}.\mspace{14mu} 2} \right) \end{matrix}$

Since individual stroke volume SV is a constant parameter and different activities definitely require different cardiac output, energy consumption (or metabolic rate at maximum activity MRMA) according to Eq.1 has to obey proportion

$\begin{matrix} {\frac{MRMA}{PMRMA} = \frac{HRMA}{HRR}} & \left( {{Eq}.\mspace{14mu} 3} \right) \end{matrix}$

Metabolic rate is measured in Metabolic Equivalent of Task (MET) which is a physiological measure expressing the energy cost of physical activities:

${1\mspace{14mu} {MET}} = {1\mspace{14mu} \frac{Kcal}{{kg} \cdot {hr}}}$

Physical activity MET Light intensity activities <3 Sleeping 0.9 watching television 1.0 writing, desk work, typing 1.5 walking, 1.7 mph (2.7 km/h), level ground, strolling, very slow 2.3 walking, 2.5 mph (4 km/h) 2.9 Moderate intensity activities 3 to 6 bicycling, stationary, 50 watts, very light effort 3.0 walking 3.0 mph (4.8 km/h) 3.3 calisthenics, home exercise, light or moderate effort, general 3.5 walking 3.4 mph (5.5 km/h) 3.6 bicycling, <10 mph (16 km/h), leisure, to work or for pleasure 4.0 bicycling, stationary, 100 watts, light effort 5.5 sexual activity 5.8 Vigorous intensity activities >6 jogging, general 7.0 calisthenics (e.g. pushups, situps, pullups, jumping jacks), heavy, 8.0 vigorous effort running jogging, in place 8.0 rope jumping 10.0

Conservative Estimate of Dangerous Activity MRMA-6 MET.

According to James L. Holly, MD the best metabolic rate is observed for an adults at the age of 20 with its average reduction by 4% every decade for males and 3% for females for who metabolic rate is 13% lower than for males. Further analysis of presented in this publication data reveals the following expression for metabolic rate at maximum activity:

$\begin{matrix} {{{MRMA}({MET})} = \left\{ \begin{matrix} {6*0.96^{\frac{{AGE} - 20}{10}}} & {{for}\mspace{14mu} {male}} \\ {5.2*0.97^{\frac{{AGE} - 20}{10}}} & {{for}\mspace{14mu} {female}} \end{matrix} \right.} & \left( {{Eq}.\mspace{14mu} 4} \right) \end{matrix}$

Personal Metabolic Rate of an individual PMRMA is the amount of energy the body needs to function at a maximum activity with resting heart rate HRR. PMRMA can be defined from individual metabolic rate BMR which is number of Kcal required by a given body to support vital functions for the entire day while at rest. Currently accepted standard for basal metabolic rate BMRS of a healthy individual of ideal weight IW is Mufflin-St.Jeor equation:

$\begin{matrix} {{{BMRS}\mspace{14mu} \left( \frac{Kcal}{day} \right)} = {{10*{IW}} + {625*H} - {4.92*{AGE}} + G}} & \left( {{Eq}.\mspace{14mu} 5} \right) \end{matrix}$ Ideal weight divine equation IW (Kg)=A+90.55·(H−1.524)  (Eq.6)

where constant

$A = \left\{ {{\begin{matrix} {50.0\mspace{14mu} {for}\mspace{14mu} {men}} \\ {45.5\mspace{14mu} {for}\mspace{14mu} {women}} \end{matrix}\mspace{14mu} {while}\mspace{14mu} {gender}\mspace{14mu} G} = \left\{ \begin{matrix} {+ 5} & {{for}\mspace{14mu} {men}} \\ {- 161} & {{for}\mspace{14mu} {women}} \end{matrix} \right.} \right.$

Conversion into metabolic equivalent of task MET reveals expression

             (Eq.  7) ${{BMRS}\mspace{14mu} ({MET})} = \frac{{10 \cdot \left\lbrack {A + {90.55 \cdot \left( {H - 1.524} \right)}} \right\rbrack} + {625 \cdot H} - {4.92 \cdot {AGE}} + G}{24 \cdot \left\lbrack {A + {90.55 \cdot \left( {H - 1.524} \right)}} \right\rbrack}$

Normalization of individual metabolic rate BMR to the standard one BMRS (the same person would have in case of being in a perfect health) requires two corrections for:

-   -   actual weight M (Kg) leading to coefficient

$\frac{BMR}{DMRS} = \frac{M}{A + 90.55 - \left( {{II} - 1.524} \right)}$

and

-   -   blood pressure (mean arterial blood pressure MAP) which, in         assumption of constant peripheral resistance of pulmonary system         R and in accordance with Eq.2 provides with

$\frac{BMR}{BMRS} = \frac{{MAP}_{actual}}{{MAP}_{desired}}$

In general, mean arterial pressure can be defined as

$\begin{matrix} {{MAP} = {{DBPR} + {0.01\left( {{SBPR} - {DBPR}} \right){\exp \left( {4.14 - \frac{40.74}{HR}} \right)}}}} & \left( {{Eq}.\mspace{14mu} 8} \right) \end{matrix}$

For desired blood pressure at 120×80 mm Hg, the second correction coefficient can be defined as

$\begin{matrix} {\frac{BMR}{BMRS} = \frac{{DBPR} + {0.01\left( {{SBPR} - {DBPR}} \right)*{\exp \left( {4.14 - \frac{40.74}{HRR}} \right)}}}{80 + {0.01\left( {120 - 80} \right)*{\exp \left( {4.14 - \frac{40.74}{HRR}} \right)}}}} & \left( {{Eq}.\mspace{14mu} 9} \right) \end{matrix}$

Thus, equation for BMR measured in MET becomes:

$\begin{matrix} {\mspace{670mu} {\left( {{Eq}.\mspace{14mu} 10} \right){{BMR} = {M*\frac{{10 \cdot \left\lbrack {A + {90.55 \cdot \left( {H - 1.524} \right)}} \right\rbrack} + {625 \cdot H} - {4.92 \cdot {AGE}} + G}{24 \cdot \left\lbrack {A + {90.55 \cdot \left( {H - 1.524} \right)}} \right\rbrack^{2}}*\frac{\left\lbrack {{DBPR} + {0.01{\left( {{SBRP} - {DBPR}} \right) \cdot {\exp \left( {4.14 - \frac{40.74}{HRR}} \right)}}}} \right\rbrack}{\left\lbrack {80 + {0.01{\left( {120 - 80} \right) \cdot {\exp \left( {4.14 - \frac{40.74}{HRR}} \right)}}}} \right\rbrack}}}}} & \; \end{matrix}$

Mean metabolic rate for above average physical work/exercise (PMRMA) is usually 2.4 times higher than BMR, or measured in MET

            (Eq.  11)  ${PMRMA} = {M*\frac{A + {90.55 \cdot \left( {H - 1.524} \right)} + {62.5 \cdot H} - {0.492 \cdot {AGE}} + {0.1 \cdot G}}{\left\lbrack {A + {90.55 \cdot \left( {H - 1.524} \right)}} \right\rbrack^{2}}*\frac{{DBPR} + {0.01\left( {{SBPR} - {DBPR}} \right)*{\exp \left( {4.14 - \frac{40.74}{HRR}} \right)}}}{80 + {0.01\left( {120 - 80} \right)*{\exp \left( {4.14 - \frac{40.74}{HRR}} \right)}}}}$

Hence, as it follows from Eq.3 dangerous (maximum allowable) heart rate can be evaluated as:

            (Eq.  12a) ${HRMA} = \frac{\begin{matrix} {6*0.96^{\frac{{AGE} - 20}{10}}*{HRR}*\left\lbrack {80 + {0.01{\left( {120 - 80} \right) \cdot}}} \right.} \\ {\left. {\exp \left( {4.14 - \frac{40.74}{HRR}} \right)} \right\rbrack*\left\lbrack {50 + {90.55 \cdot \left( {H - 1.524} \right)}} \right\rbrack^{2}} \end{matrix}}{\begin{matrix} {\left\lbrack {{DBPR} + {0.01{\left( {{SBPR} - {DPBR}} \right) \cdot {\exp \left( {4.14 - \frac{40.74}{HRR}} \right)}}}} \right\rbrack*} \\ {\left\lbrack {50 + {90.55 \cdot \left( {H - 1.524} \right)} + {62.5 \cdot H} - {0.492 \cdot {AGE}} + {0.1 \cdot 5}} \right\rbrack \cdot M} \end{matrix}}$

for men and

            (12b) ${HRMA} = \frac{\begin{matrix} {5.2*0.97^{\frac{{AGE} - 20}{10}}*{HRR}*\left\lbrack {80 + {0.01{\left( {120 - 80} \right) \cdot}}} \right.} \\ {\left. {\exp \left( {4.14 - \frac{40.74}{HRR}} \right)} \right\rbrack*\left\lbrack {45.5 + {90.55 \cdot \left( {H - 1.524} \right)}} \right\rbrack^{2}} \end{matrix}}{\begin{matrix} {\left\lbrack {{DBPR} + {0.01{\left( {{SBPR} - {DPBR}} \right) \cdot {\exp \left( {4.14 - \frac{40.74}{HRR}} \right)}}}} \right\rbrack*\left\lbrack {45.5 +} \right.} \\ {\left. {{90.55 \cdot \left( {H - 1.524} \right)} + {62.5 \cdot H} - {0.492 \cdot {AGE}} - {0.1 \cdot 161}} \right\rbrack \cdot M} \end{matrix}}$

for women

This equation allows to define percentage of heart rate increase at maximum activity for a person taking no medications for changing blood pressure and pulse

$\begin{matrix} {{PHRI} = \frac{{HRMA} - {HRR}}{HRR}} & \left( {{Eq}.\mspace{14mu} 13} \right) \end{matrix}$

In case medication sets up different heart rate at rest, the limit of dangerous activity should be computed as

$\begin{matrix} {{HRMA}_{{with}\mspace{14mu} {medication}} = {{HRR}_{{with}\mspace{14mu} {medication}} \cdot \left\lbrack {1 + \left( \frac{{HRMA} - {HRR}}{HRR} \right)_{{without}\mspace{14mu} {medication}}} \right\rbrack}} & \left( {{Eq}.\mspace{14mu} 14} \right) \end{matrix}$

Based on the fact that systolic cycle is two times shorter the diastolic one there is another expression for mean arterial blood pressure:

$\begin{matrix} {{MAP} = {{DBP} + \frac{{SBP} - {DBP}}{3}}} & \left( {{Eq}.\mspace{14mu} 15} \right) \end{matrix}$

where DBP and SBP are current diastolic and systolic blood pressure respectively.

Hence, Eq.8 and Eq.15 reveal equation

$\begin{matrix} {{{DBP} + \frac{{SBP} - {DBP}}{3}} = {{DBPR} + {0.01 \cdot \left( {{SBPR} - {DBPR}} \right) \cdot {\exp \left( {4.14 - \frac{40.74}{HR}} \right)}}}} & \left( {{Eq}.\mspace{14mu} 16} \right) \end{matrix}$

where HR is heart rate at given activity

Under the assumption that the ratio of systolic blood pressure to diastolic blood pressure remains the same under any activity

$\frac{SBPR}{DBPR} - \frac{SBP}{DBP}$

solution of Eq.16 is:

$\begin{matrix} {{{SBP} = {{SBPR} \cdot \frac{3 + {0.03 \cdot \left( {\frac{SBPR}{DBPR} - 1} \right) \cdot {\exp \left( {4.14 - \frac{40.74}{HR}} \right)}}}{\frac{SBPR}{DBPR} + 2}}}{{DBP} = {{DBPR} \cdot \frac{3 + {0.03 \cdot \left( {\frac{SBPR}{DBPR} - 1} \right) \cdot {\exp \left( {4.14 - \frac{40.74}{HR}} \right)}}}{\frac{SBPR}{DBPR} + 2}}}} & \left( {{Eq}.\mspace{14mu} 17} \right) \end{matrix}$

with three related to discussed subject consequences:

-   -   State of rest (SBP=SBPR and HR=HRR) does not depend on blood         pressure and can be defined as heart rate

${HRR} = {\frac{40.74}{4.14 + {\ln \; 0.03}} \cong {64\mspace{14mu} {beats}\text{/}{\min.}}}$

This number, in case no-medication-heart-rate is known or recalled, can be used for computing heart rate at maximum activity in Eqs.12a and 12b and further in Eq.14 for computing maximum allowed heart rate HRMA for a user taken prescription drug;

-   -   Pulse is an indicator of blood pressure which dangerous level         could be estimated as

$\begin{matrix} {{{SBPMA} = {{SBPR} \cdot \frac{3 + {0.03{\left( {\frac{SBPR}{DBPR} - 1} \right) \cdot {\exp \left( {4.14 - \frac{40.74}{HRMA}} \right)}}}}{\frac{SBPR}{DBPR} + 2}}}{{DBPMA} = {{SBPMA} \cdot \frac{DBPR}{SBPR}}}} & \left( {{Eq}.\mspace{14mu} 18} \right) \end{matrix}$

-   -   personal instantaneous metabolic rate (PIMR), or measured in         Kcal per minute required for current activity energy, can be         estimated by continuously (every minute) monitored heart rate in         accordance with modified Eq.10 as follows

$\begin{matrix} {{PIMR} = {M^{2}*\frac{A - 138 + {153.05 \cdot H} - {0.492 \cdot {AGE}} + {0.1 \cdot G}}{144 \cdot \left\lbrack {A + {90.55 \cdot \left( {H - 1.524} \right)}} \right\rbrack^{2}}*\frac{\left\lbrack {{DBPR} + {0.01\left( {{SBPR} - {DBPR}} \right)*{\exp \left( {4.14 - \frac{40.74}{HR}} \right)}}} \right\rbrack}{\left\lbrack {80 + {0.01\left( {120 - 80} \right)*{\exp \left( {4.14 - \frac{40.74}{HRR}} \right)}}} \right\rbrack}}} & \left( {{Eq}.\mspace{14mu} 19} \right) \end{matrix}$

Replacement of instantaneous heart rate (HR) in the above equation by daily (average) heart rate

$\overset{\_}{HR} = \frac{{HRR} + {HRMA}}{2}$

leads to evaluation of required daily energy consumption (RDEC) as

$\begin{matrix} {{RDEC} = {10*M^{2}*\frac{A - 138 + {153.05 \cdot H} - {0.492 \cdot {AGE}} + {0.1 \cdot G}}{\left\lbrack {A + {90.55 \cdot \left( {H - 1.524} \right)}} \right\rbrack^{2}}*\frac{\left\lbrack {{DBPR} + {0.01\left( {{SBPR} - {DBPR}} \right)*{\exp \left( {4.14 - \frac{40.74}{\overset{\_}{HR}}} \right)}}} \right\rbrack}{\left\lbrack {80 + {0.01\left( {120 - 80} \right)*{\exp \left( {4.14 - \frac{40.74}{HRR}} \right)}}} \right\rbrack}}} & \left( {{Eq}.\mspace{14mu} 20} \right) \end{matrix}$

Further comparison of its value with actually provided by food during the day energy (PFE) allows to watch over or improve personal diet. On average, carbohydrates (sugars and starches) and proteins provide approximately 4 Kcal/g, lipids (fats) produce 9 Kcal/g, and the oxidation of alcohol produces 7 Kcal/g. Thus, daily balance evaluation could be in favor of gain, loss, or stable weight:

DISCUSSION

Derived equations for a personal overstressed level of heart beats allow proposing a new electronic device capable of:

-   -   Estimating expected alarm conditions of dangerous activity by         comparing heart rate at rest with the instantaneous one. For         randomly selected individuals “static” analysis reveals         trustworthy results.     -   Automatically updating age information along with changing         health conditions affecting heart rate at rest (see table         below).     -   Input new data regarding change of weight, medication taken, and         blood pressure.     -   Predict current and dangerous level of blood pressure.     -   Monitor energy output (see table below) and compare it with the         input (if known) resulting in weight loss or gain.     -   Further modifications for wireless communications with         authorized parties.

While illustrative embodiment of the invention has been shown and described, numerous variations and alternate embodiments, including eliminating one or more of the steps or elements presented herein, will occur to those skilled in the art. Such variations and alternate embodiments are contemplated and can be made without departing from the spirit and scope of the invention as mentioned in the appended claims.
